OBJECTIVE: To study the long-term clinical effect of multicenter multidisciplinary treatment (MDT) in children with renal malignant tumors. METHODS: A retrospective analysis was performed on the medical data of 55 children with renal malignant tumors who were diagnosed and treated with MDT in 3 hospitals in Hunan Province from January 2015 to January 2020, with GD-WT-2010 and CCCG-WT-2016 for treatment regimens. A Kaplan-Meier survival analysis was used to analyze the survival of the children. RESULTS: Of the 55 children, 10 had stage I tumor, 14 had stage Ⅱ tumor, 22 had stage Ⅲ tumor, 7 had stage IV tumor, and 2 had stage V tumor. As for pathological type, 47 had FH type and 8 had UFH type. All children underwent complete tumor resection. Of the 55 children, 14 (25%) received preoperative chemotherapy. All children, except 1 child with renal cell carcinoma, received postoperative chemotherapy. Among the 31 children with indication for radiotherapy, 21 (68%) received postoperative radiotherapy. One child died of postoperative metastasis. The incidence rate of FH-type myelosuppression was 94.4%, and the incidence rate of UFH-type myelosuppression was 100%. The median follow-up time was 21 months and the median survival time was 26 months for all children, with an overall survival rate of 98% and an event-free survival rate of 95%. CONCLUSIONS Multicenter MDT has the advantages of high success rate of operation and good therapeutic effect of chemotherapy in the treatment of children with renal malignant tumors, with myelosuppression as the most common side effects, and radiotherapy is safe and effective with few adverse events. Therefore, MDT has good feasibility, safety, and economy.

Background:Clinical outcomes of undifferentiated arthritis (UA) are diverse,and only 40 ％ of patients with UA develop rheumatoid arthritis (RA) after 3 years.Discovering predictive markers at disease onset for further intervention is critical.Therefore,our objective was to analyze the clinical outcomes of UA and ascertain the predictors for RA development.Methods:We performed a prospective,multi-center study from January 2013 to October 2016 among Chinese patients diagnosed with UA in 22 tertiary-care hospitals.Clinical and serological parameters were obtained at recruitment.Follow-up was undertaken in all patients every 12 weeks for 2 years.Predictive factors of disease progression were identified using multivariate Cox proportional hazards regression.Results:A total of 234 patients were recruited in this study,and 17 (7.3％) patients failed to follow up during the study.Among the 217 patients who completed the study,83 (38.2％) patients went into remission.UA patients who developed RA had a higher rheumatoid factor (RF)-positivity (42.9％ vs.16.8％,x2=8.228,P=0.008),anti-cyclic citrullinated peptide (CCP) antibodypositivity (66.7％ vs.10.7％,x2 =43.897,P ＜ 0.001),and double-positivity rate of RF and anti-CCP antibody (38.1％ vs.4.1％,x2 =32.131,P ＜ 0.001) than those who did not.Anti-CCP antibody but not RF was an independent predictor for RA development (hazard ratio 18.017,95％ confidence interval:5.803-55.938;P ＜ 0.001).Conclusion:As an independent predictor of RA,anti-CCP antibody should be tested at disease onset in all patients with UA.

Objective:To study the influences of Mycoplasma penumoniae capsular polysaccharide (CPS) on the phagocytosis and membrane molecules expression of the human peripheral blood mononuclear cells derived dendritic cells by binding to dendritic cell-specific intercellular adhesion molecule-3-grabbing nonintegrin (DC-SIGN),so as to know the effect of CPS on the maturation of dendritic cells.Methods:M.pneumoniae strain was cultivated and CPS was extracted.Human peripheral blood mononuclear cells were separated and induced to dendritic cells,then identified the cells by flow cytometry and observation under the microscope.CPS was used to treat dendritic cells or cells pretreated with DC-SIGN monoclonal antibody,and then FITC-dextran phagocytosis and surface markers CD83,HLA-DR,CD80 and CD86 were detected by flow cytometry.Results:The dendritic cells tended to form colony groups.The positive rate of CD11c molecule in the cultured dendritic cells was about 86.27％.After stimulated by CPS,the FITC-dextran fluorescence mean intake by dendritic cells were increased (P＜0.05),while the cell surface membrane molecules CD83,HLA-DR,CD80 and CD86 were decreased significantly when compared with the PBS treated control cells(P＜0.05).When blocked DC-SIGN with the monoclonal antibody,the FITC-dextran fluorescence mean and membrane molecules expression had no statistical difference with the control cells(P＞0.05).Conclusion:M.pneumoniae CPS can promote the phagocytic function of DC and inhibit the expression of CD83,HLA-DR,CD80 and CD86.

Background:For Chinese patients with hepatocellular carcinoma (HCC),surgical resection is the most important treatment to achieve long-term survival for patients with an early-stage tumor,and yet the prognosis after surgery is diverse.We aimed to construct a scoring system (Shanghai Score) for individualized prognosis estimation and adjuvant treatment evaluation.Methods:A multivariate Cox proportional hazards model was constructed based on 4166 HCC patients undergoing resection during 2001-2008 at Zhongshan Hospital.Age,hepatitis B surface antigen,hepatitis B e antigen,partial thromboplastin time,total bilirubin,alkaline phosphatase,γ-glutamyltransferase,α-fetoprotein,tumor size,cirrhosis,vascular invasion,differentiation,encapsulation,and tumor number were finally retained by a backward step-down selection process with the Akaike information criterion.The Harrell's concordance index (C-index) was used to measure model performance.Shanghai Score is calculated by summing the products of the 14 variable values times each variable's corresponding regression coefficient.Totally 1978 patients from Zhongshan Hospital undergoing resection during 2009-2012,808 patients from Eastern Hepatobiliary Surgery Hospital during 2008-2010,and 244 patients from Tianjin Medical University Cancer Hospital during 2010-2011 were enrolled as external validation cohorts.Shanghai Score was also implied in evaluating adjuvant treatment choices based on propensity score matching analysis.Results:Shanghai Score showed good calibration and discrimination in postsurgical HCC patients.The bootstrap-corrected C-index (confidence interval [CI]) was 0.74 for overall survival (OS) and 0.68 for recurrence-free survival (RFS) in derivation cohort (4166 patients),and in the three independent validation cohorts,the CIs for OS ranged 0.70-0.72 and that for RFS ranged 0.63-0.68.Furthermore,Shanghai Score provided evaluation for adjuvant treatment choices (transcatheter arterial chemoembolization or interferon-α).The identified subset of patients at low risk could be ideal candidates for curative surgery,and subsets of patients at moderate or high risk could be recommended with possible adjuvant therapies after surgery.Finally,a web server with individualized outcome prediction and treatment recommendation was constructed.Conclusions:Based on the largest cohort up to date,we established Shanghai Score-an individualized outcome prediction system specifically designed for Chinese HCC patients after surgery.The Shanghai Score web server provides an easily accessible tool to stratify the prognosis of patients undergoing liver resection for HCC.

OBJECTIVETo study the effects of Weipixiao (胃痞消, WPX) on Wnt pathway-associated proteins in gastric mucosal epithelial cells from rats with gastric precancerous lesions (GPL).

METHODSSprague Dawley rats were randomly divided into control, model, vitacoenzyme (0.2 g·kg(-1)·day(-1)), WPX high-dose (H-WPX, 15 g·kg(-1)·day(-1)), WPX medium-dose (M-WPX, 7.5 g·kg(-1)·day(-1)) and WPX low-dose (L-WPX, 3.75 g·kg(-1)·day(-1)) groups. After successfully establishing the GPL model, the rats were consecutively administered WPX or vitacoenzyme by gastrogavage for 10 weeks. Differential expression of Leucine-rich repeat-containing G-proteincoupled receptor 5 (Lgr5), matrix metalloproteinase-7 (MMP-7), Wnt1, Wnt3a, and β-catenin in gastric mucosal epithelial cells in all groups were immunohistochemically detected, and the images were taken and analyzed semiquantitatively by image pro plus 6.0 software.

RESULTSGastric epithelium in the model group showed significantly higher expression levels of Lgr5, MMP-7, Wnt1, Wnt3a and β-catenin than those of the control group(P<0.01). Interestingly, we also observed Lgr5+ cells, which generally located at the base of the gastric glandular unit, migrated to the luminal side of gastric epithelium with GPL. The expression levels of Lgr5, MMP-7, Wnt1, and β-catenin were all down-regulated in the L-WPX group as compared with those of both model and vitacoenzyme groups (P<0.05). A similar, but nonsignificant down-regulation in expression level of Wnt3a was noted in all WPX groups (P>0.05).

CONCLUSIONOur findings suggested that the therapeutic mechanisms of WPX in treating GPL might be related with its inhibitory effects on the expressions of Lgr5, MMP-7, Wnt1, β-catenin and the aberrant activation of Wnt/β-catenin pathway.

To study the effect of Siwu decoction on the function and expression of P-glycoprotein (P-gp) in Caco-2 cells. The Real-time quantitative poly-merase chain reaction (Q-PCR) was used to analyze the mRNA expression of MDR1 gene in Caco-2 cells. Flow cytometer was used to study the effect of Siwu decoction on the uptake of Rhodamine 123 in Caco-2 cells, in order to evaluate the efflux function of P-gp. Western blotting method was used to detect the effect of Siwu decoction on the P-gp protein expression of Caco-2 cells. Compared with the blank control group, after Caco-2 incubation with Siwu decoction at concentrations of 3.3, 5.0, 10.0 g x L(-1) for 24, 48, 72 h, the mRNA expression of MDR1 was up-regulated, suggesting the effect of Siwu decoction in inducing the expression of MDR1. After the administration with Siwu decoction in Caco-2 cells for 48 h, the uptake of Rhodamine 123 in Caco-2 cells decreased by respectively 16.6%, 22.1% (P < 0.05) and 45.4% (P < 0.01), indicating that the long-term administration of Siwu decoction can enhance the P-gp efflux function of Caco-2 cells. After the incubation of Caco-2 cells with Siwu decoction for 48 h, the P-gp protein expression on Caco-2 cell emebranes, demonstrating the effect of Siwu decoction in inducing the protein expression of P-gp.
